2 Claims. (Cl. 101-394) The present invention relates to the art of newspaper publication, and more particularly to the registration of color printing plates or casts used on rotary cylinders of a newspaper printing press.

It is well known to those skilled in the art that a separate cut or printing plate must be used to print each color of a colored picture being reproduced including black, if black is used. Each one of the several casts or plates must be lined-up or registered on the press in order that the picture will be properly printed. This registration is not too diilicult a task on a at-bed or letter-press where the cut can be comparatively easily moved, but when color is to be reproduced on a newspaper rotary press, considerable diiculty is often encountered because the circular printing plates cannot be moved as easily and in many cases not far enough to effect a register with the other mating color plates, or casts.

In newspaper work human error as well as mechanical failure may easily enter into the making of out-of-register` stereotype casts or plates. The several matrices rolled from the properly composed type chases may not shrink evenly or alike; the operator may make an uneven trim on the edge of the matrix; the matrix may not be placed properly within the stereotype casting machine, resulting in a stereotype cast with the image twisted or out of line with its longitudinal direction of roll. Any one of these and other factors may cause the plates to be out-ofregister when placed upon the printing cylinders. This out-of-register will not be detected until the presses have been started and a number of papers printed. Some adjustment may then be made, as stated hereinabove, which amounts to approximately a total of thirty thousandths of an inch of movement from top to bottom with respect to the page being printed. It is necessary to stop the presses each time such an adjustment is made. If this adjustment is not sullicient to get the plates in register, the plates must be made over, or run as they are, which isusually the case in newspaper work because time schedules will not permit the remaking of the plates.

One method for eilecting better registry of the plates has been devised in the scoring or placing of grooves along the four sides of the type chase which makes a raised line on the matrix by which the stereotype operator trims the matrix. This helps in the registering of the plates, but human error in trimming all matrices alike is most prevalent at this stage of the operation.

Another improvement has been the use of thermostatically controlled heat in the vacuum operated matrix shrinking machines. Theoretically all matrices should shrink alike, but some matrices contain more moisture than others and consequently do not shrink alike. This variation in shrinkage is so slight that it will not be detected until the presses start printing.

The results attainedl by my invention has been sought for a long time, but has never been attained.

'1o The present 1nvent1on overcomes the above defects in producingregistered rotary colorplates. by providing.

a means of accurately checking the size of the matrix and the printing plates, or casts.

The principal object of the present invention is to provide register marks for checking the register of rotary color plates at any stage during the process of their manufacture.

Another object is to provide register marks on the newspaper type chases that are in a ixed position and do not have to be lined up for registry. l

Another object is to provide a means of trimming the edges of the matrix while they are held in registering position.

Still another object is to provide a means for checking the variation of shrinkage, if any, of the several matrices.

Yet another object is to provide a -means for identically registering each printing plate for the iinal milling operation which cuts the gripping pockets therein.

The present invention attains these several objects by providing register marks upon the type chases used in the page make-up which are transmitted to the matrix when molded. A vacuum operated trim table holds the finished matrix in register by the register marks while three sides of the matrix is trimmed to size. This vacuum table may be used to further check the register of the various matrices after the matrices have been heated for shrinking. During the stereotyping operation the matrix transfers the register marks to the stereotype cast or printing plate. A plate checking -device is provided to check the register of each plate and identically position each plate for drilling additional register holes which act to register each plate during the last stage of the milling operation.

'These side designations have reference to the,` makeup ofi the newspaper pageto be printed therefrom. The type chase 1 has a `conventional lock-up bar 6, adjacent the bottom end 3,. and` lock-up 4bar 7 adjacent theleft side 5, and a type or engraving space area as indicatedv by the numeral- 3. The type chase 1 has conventional trim grooves in the top surface of its ends 2 and 3 and lock-up bars 6 and 7, as indicated by the lines 10 in Fig. 1anjd as shown more clearly in Fig. 4. As, shown yin Fig. 4, the groove 10 is located adjacent but outwardly from the shoulder 11, along the type side of the type chase 1.

. The above description discloses a conventionalfnewspaper type chase upon which my device is proposed to be installed.

It is conventional practice in printing color work to place a register mark upon the vertical and horizontal center lines of the picture or working drawings before making engravings therefrom. .These marks aroused in lining up the cut when the diiierentfcolorsarebeing printed, and after completion of the printing, the printedregister marks are trimmed off of the printcdvproduct. It is not practical to use such register marks in newspaper printing where the newspapers are printed from a rotary press using a continuous roll of paper stock, because the marks cannot easily be trimmed off and the Arotaryfplates cannot be moved suliciently to affect a register as` explained hereinabove.

In order to place the invention into operation, the vertical and horizontal center lines of the type area 8 of the type chase 1, are located as indicated by the reference numerals 15 and 16, respectively.. A. register mark 17 is then placed upon theside 4. and end 2, inside of the groove 10.. Since thel-ock-up bars G .and 7 are I novablev and do not assume the identical position ,in4 loeloup,:eachA time a. chase is made up, due to the variation in the/,thickness of metal used in the make-up o f a page within the. chase, it is necessary to provide a means of locating theregister marks on the bottom 3 and the side 5in such manner that they will be rigidly positioned.- This is done, asishov/n in Fig..2, by: cutting .a slot in the top of thefendandithe side 5 to receive a rectangular plate 1S which is rigidly attached to the end 3 and the side 5 by screws 19, having one end parallel with the outer edge'of the-chaseland the opposite end extending inwardly toward thetype area 8 substantially equidistant with the lock-up V-bars @and 7,

respectively, when in make-up. position. Themovable' lock-up bars 6 and '7 are similarly slotted as shown by the numerals 2@ and 21 in Fig. l.. The slots 20'and 21 are substantially the same depth as the slots. in the end 3 and the side S, which hold the plates 18,wit'h the top of the plate 1S in the same plane as the top of the end-lir.v and Vthe side 5. The slots Z0 and 21-are substantiallywider than the vplates 1S, to allowV for theendwise movement of the bar 7 and uneven movement of the bar 6 as thetype chase .is llocloedA-up. A registerrmark l? isplacedadjacent .the innermost. end of the plates lit ,uponA thcfyertical and horizontal center lines 15 and 16, respectively, and inside ofv theutr'irn 'line or groove 1t).

Illustrated in Fig. 2.isl va register-'mark ITI-.which is formed, `as by drilling, .a iat bottomed circularfrecess with a substantially vertical wall 22 and leaving a centrally disposedflat topped -upstanding conical core23 therein. The depth of t-he register mark in the plate 18 is sufficient to insure a definite impression in the matrix 30 as explained hereinbelow. These register marks 17 are hereinafter referred to as the center-line register marks.

After the type chase ismade-up, a matrix 30 is molded from the chase in the ,conventional lmanner, not shown. The matrix 30 is indicated by the dotted lines in Fig. l, and the sides 31.*32` extend outwardly upon vvthe side 4 and the bar 7 ofthe ty-pe chase 1 a substantial distance to cover the grooves 10 and the register marks 17 on the horizontal center line 16. Similarly the ends 33 and 34 which was in contact with the type upwardand thereafter known as the front 3S of the matrix 30.' The end 33 becomes the top and the end 34 becomes `the bottom of the matrix. The center-line register marks 17. are molded into the matrix 30, as shown in Fig. 5; The register marks 17A are shown on the vertical and horizontal center lines 15 and 16; but it is to be understood that these center line positions, as shown on the matrix 30,- are thecenter linesof the type area 8 fromthe type chase 1, and are not molded into the matrix 30, and are not neces sat1-ily the center 'lines o f lthe matrix; The matrix 30 is laid upon the ymade-up type chase 1 in approximately the proper position before molding and therefore the s ides andends 'of the matrix quite frequently are not parallel with'the trim grooves 10. The grooves 10 make a raised line or narrowlridge 10A upon lthe front 35 of the matrix (Fig. 5') as itis molded'froin the type chase. These linesl 10A1areused to trim the sides andends of the matrix to squareit-up before casting the stereotype Vplate as hereinafter explained.

As `is illustrated in Fig. 6, the center-'line register marks 17A, ,on the matrix 30, are just the reverseyof themark'17 within the surface ofthe type chase 1, comprising an upstanding flat topped circular projection 36, having a centrally disposed ilatk bottomed inverted conical recess 37 therein.

The centerfline register marks 17A are used for checkingthe matrices asv-hereinafter described, but are not properly located for checking the registry of the stereotype printing lplatesgwhichV are made from the register marked matrices; A pair of register marks 40 arel placed side by side in the upper sur-face `of the top numbered 2 of the type chase '1, at a selected position adjacentpthe cornersr of the `type chase area 8. Identical register marks 40 are similarly positioned at the 'bottom 3 -of the type chase 1, in rectangular plates 41 rigidly attached to thejbottom 3 by screws 42, by cutting slots in the top of the v bottom 3v and `the bar V6 as described for the platejl hereinabove. Clearly illustr-ated in Fig. 3,r is atypical register mark 40, comprisingfa flat bottomed conical recess. rvIhese register marks 40 are hereinafter-,referred toasthe fcorner .z 10A, shown in Eig. 5.

These Cerner; resister-marks 40A particularly from side to side of the page to be printed, in order that narrower rolls of paper may be used in the printing operation thus effecting a substantial savings in the amount of paper consumed. Some shrinkage is also present in the top to bottom measurement of the matrix. Approximately one-third of the matrix shrinkage occurs in the first shrinking operation. The matrices do not all shrink evenly nor the same amount due to the variation in the amount of moisture in them and the heat of the shrinking chamber andother factors such as atmospheric conditions, etc.

After this first shrinking operation the matrices are backed or packed, and the top and the right and left sides are trimmed oi along the trim lines A, formed by the grooves 10. This trimming is done by a conventional paper knife while the matrix is held by the operator guiding the matrix along the path of the knife with one hand while operating the knife with the other hand. The bottom end portion of the matrix is trimmed only slightly in order that the matrix will fit into the final shrinking heat machine. In this iinal heating for shrinking, where approximately two-thirds of the shrinkingtakes place, the matrix is held in place by a vacuum pull upon its back side which prevents too fast a shrinkage while approximately 350 F. of heat is applied to the matrix. After this nal heat shrinking, the matrix is presumed to be dry and to have shrunk as much as it will. The matrix is then given its final trim along the bottom end 34. Before placing the matrix within the stereotype casting machine, the matrix is again heated to approximately 350 F. for preventing bubbles in the printing plate metal which is normally heated to approximately 600 F. before it contacts the matrix. The stereotype machine cuts or saws the printing plate to the proper width before it is removed from the stereotype machine. If the matrix is not properly seated with one of its sides 31 or 32 in contiguous contact with its slot within the stereotype machine, .or if the side placed downward has been trimmed unevenly, or if the top 33 or bottom 34 has not been trimmed in parallel relation, the matrix will have the type impression thus made in twisted relation to the longitudinal axis of the casting cylinder of the stereotype machine. This results in a printing plate having a twisted image that cannot be registered with its mating colors on the printing press.

The plate is then taken from the stereotype machine and placed within an auto-miller machine where the plate is milled from the under side to the desired thickness, and printing press cylinder gripping pockets or grooves are cut in it. This auto-miller machine also cools the plate to approximately room temperature. Thereafter the plates are routed as may be necessary.

The above description of the stereotyping operation is conventional with most newspaper operations, and is recited here only for the purpose of more clearly relating the present invention to this type of operation.

As a means of comparatively checking the shrinkage ofthe several matrices used in printing color, a device for registering and holding the matrices While they are trimmed is provided. This registerer and trimmer comprises a box or table-like stand 50 (Fig. 8), having a substantially flat foraminated top 51 connected to a vacuum pump 52 in a conventional manner. The dimensions of the top are equal to the size of the matrix trim lines 10A after the first shrinkage of the matrix 30. The top 51 is equipped with preferably three conventional paper knives 53 for trimming the sides 31 and 32 and the top 33 of the matrix. A substantially ilat rectangular plate 55 having substantially smaller proportions than the top 51, is held in fixed spaced superposed central relation to the top 51 by a pair of elongated bracket arms 56 which are attached, as by welding,ltoone end of the stand 50 and to the upper surface of the plate S5.` This plate has side edges 57 and 58 and l ends 59 and 60 which are substantially parallel with the side and end edges, respectively, of the top 51. A register indicator 54, comprising a substantially flat rectangular metal base 61 which is longitudinally slidably disposed up-f on the vertical and horizontal center line of the plate 55 adjacent each side 57-58 and end 59 and 60, respectively, between a pair of co-operating angle iron guide rails 62 and 63 (Fig. 1l), rigidly attached, as by welding, to the upper surface of the plate 55. An elongated register arm 64 is pivotally attached, at a selected point intermediate its ends, to the upper surface of the base 61 between a pairI of co-operating upstanding bosses 65 and 66 by a pivot pin 67. The register arm 64 is longitudinally centrally disposed on its respective center line. An elongated conical register pin 70 is rigidly attached at one end to the lower surface of the outermost end 68 of the arm 64, with its small or tapered end 71 downward. The register pin 70 has a length great enough to reach from the horizontal position of the arm 64 to the bottom of the register mark impression 17A in the matrix 30. The circumference of the pin 70 is substantially equal to the diameter of the register mark 17A. A helically Wound tension spring 72 is vertically disposed with one end upon the base 61 and its opposite end in contact with the under surface, adjacent the end 69, of the arm 64, to vertically pivot the arm 64 and urge the register pin end 71 into the register mark 17A.

With the knives 53 in a raised position, the matrix 30 is placed atly upon ythe top 51 with the front 35 upwardly, and the top 33 `at the knife end of the top 51. The register pins 70 are placed within their respective register mark 17A, as shown in Fig. 12.. As explained hereinabove, the register .arms 64 and bases 61 are longitudinally slidably disposed upon the plate 5S to enable' each pin 70 to seat its tip end 71 .snugly within the respective yregister mark 17A. To `determine if th-e matrix has beenshrunk evenly, each register base 61 has an index arm 73 pivotally attached to the base 61, adjacent the boss 65, by a pivot pin 74. The index arm 73 is slotted and pivotally attached to the Iupper surface of the guide rail 62 by a pivot pin 75 therein. Any longitudinal movement of the arm 64 and base 61, as shown by the dotted lines (Fig. 1l), is then 'indicated by the index 4arm 73 on lthe indi-cia 76 placed upon the upper surface of the plate 55 (Fig. 9). If the matrix has been shrunk the proper amount the index arms should read at zero, for example. If lthe next matrix lof the mating color has not shrunk the same amount as the first, then one ofthe index yarms 73 will record the variation on Ithe indicial marking 76. If all matrices checked for a particular `color have identical variations, Ithen the printing plates made from lthem will register. When the matrix has been centrally positioned upon the top 51 the vacuum pump S2 is turned on and exerts a vacuum pull upon lthe back of the matrix, holding it firmly While the knives 53 are used to trim the sides 31 and 32 .and the top 33, along the Itrim lines 10A. With the vacuum pull upon the matrix 30 through the foraminated top 51 while the sides and top are being trimmed, the matrix 30 cannot move or creep thus insuring -a true cut along its sides and top. This helps to properly position the matrix within .the stereotype casting machine. After the vacuum pump 52 has been turned off, the matrix 30 is removed from the stand 50 and the bottom 34 is trimmed to lthe approximate proper length as explained hereinabove. It is thought to be evident that the matrices may be comparatively checked for the amount of shrinkage at any stage of their progress' through the stereotype operation.

The printing plates 8i) (Fig. 13), which are cast from the several matrices 30 and which have been checked for identical shrinkage, will have the register marks 17A cast therein upon the vertical and horizontal center lines of the page It-o be printed. Similarly the corner 'register marks 40A on the matrix 30 ar-e cast into the corners of the printing plate `and are flat bottomed inverted conical recesses S4 arid 85 similar to the register marks 40 of the type chase 1. A printing plate checking device 88 is provided for comparatively checking the accuracy of the plates 80, which includes a horizontally disposed arenas@ Senn-cylindrical]hol1ow,;body. 9,0, having. its arcuate 'Qutl' surface,-f acing Iupwardly andpformed to contiguously. rer ceive-the-hearing ribs 81 of the` inner surface ofa printing plate 80; The body 90 is rigidly mounted on a table 91 orother suitable stand. The, plate 80 is' placed upon the. b ody -90 (Fig. 14)- where it is centrally. positioned vertically by a :scriber arm 9 2 adjacent each corner ofthe bOdY 9.0;.Cmprising an elongated L shaped s trip metal arml having its longer l eg 9j3horizontally slidably pivoted at a selected point intermediate its -ends toa rigid depending leg 94 :of the body 9 0, by a p in 95 closely received by a longitudinal slot 9,6 in .the leg 93 (Fig. 16). The shorter leg 97 of the Iscriber arm 92, is vertically disposed andfhas a ,length great .enough to position its upper 0r free end portion 98 over the. outermost cornerregister mar-kdm Afteonicaluregisterf pin 99 isnrigidly attached ati-ts base, having its longitudinal axis Isubstantially perpendicular to the inner.` faceof the endl portion 93 ofthe leg 97. rlhe register pins 99. are `adapted to seat lWithin the corner register marks 84. The free end of the leg 93 is tapered to a point 100 and is `slidably positioned 'over .an index plate 101. A tension .spring 102, having its ends attached to the -depending leg 94 and the vertical leg 97, respectively, acts to urge the register pin 99 into the register mark 84, as shown by the dotted lines in Fig. 16. When the register pins 99 are not 4seated. within theregister marks 84 by reason of the plate 80 not being vertically centered upon the body 90, the deviation from center will be readily `discernible by the points 100 of the legs 93 indicating on lthe index plate 101. lThe plate may be circularly slid upon lthe body 90 as, for example, the .side 86 of the printing plate 80 may be lowered along one side yof the lbody thus raising the side 83. l

When a printing plate $0 has been cast from a matrix which was not properly seated within the stereotype casting box, the image will be twisted with relation to the roll of the plate when on the press cylinder. This twist will be evident by the position of points on the index plates 101, and no adjusting of the plate S0 upon thebody 90 will be able to overcome the t wist; butbeing :detected at this stage .of the process, the plate Imay be remade.

The printing plate 80 is centrally positioned longitudinally upon the body 90 by vertically disposed soribers adjacent each corner, respectively, of the body 90. Each scriber 110 'comprises an elongated `metal armrlll pivotally connected adjacent its lower end, as shown by the dotted lines of Fig. 19, by a pivot pin 113, to .a bracket 112 which yis rigidly attached to the body 90. Anelongated conical-register pin 114 is rigidly attached .att its base vat a `selected point :on the inner face of the arm 111 in a horizontal position yto enter the corner register i marks 85. The bracket 112 has a pair of outwardly flared upstanding arms 115 substantially of the sainel'ength as the arm111, and which rigidlyholds an 'indexed plate 116. The upper end lof the Yarm 111 has a tapered portion .117 which indicates upon the index plate 116 the variation `from the central position, 'if any, of the printing plate tit) upon lthebody 9d. The printing plate d@ may be slid longitudinally upon the body 9() to let the tapered ends 1.1.7V all rea-d identically upon the index plates 116. The scriber arms 111 are each pivotally hinged at a point adjacent .their lower endabove the pivot pin 113 as at 11S, and as shown in dot-ted lines (Fig. 20), to allow the upper portion-:of the arm 111 to be pivoted outwardly from the body 99 l,while placing the printing plate 3 0 thereupon. The register pin 114 isheld in Contact within its respective re rumark {ii-by a tension spring 119,ll aving .its ends atta hed` to the bracket 112 and to the inner faceof thearm 111 respectively.

Another pnrpose of the cribers .92 and 1 1@ vis to v ertically and A,longittlndinallycentrally position the printing plates 80.to'ldrill centering holes in the under side of `the printingplates by .which the several plates 30 are medicaux/held while the alito-miller, gutsLv Printingrress in a lconventional manner on a shaft 1 22'riglidl`y attached to the upper surface of the table top 91, centrally positioned within the body 90 and adjacent eachend of the same. Each drill '121 has a drilllbit'123 therein having a suitabley tapered end for drilling a center hole ori'ecess 1239 a selected distance into the metaofthe printing plate. After the printing platey SQ hasfbeen checkedfor accuracy and centered npon thel body 90, the drillsare raised by the use'o'f suitable pivoted levers and linka'gef124, allowing each drill bit'123 to pass through lits*cti-operating perforation 125 inf'thebody.` 9 0, to`drillthe center holes 1211.v The'upward`Ino\`fe'n 1e1 1't, of the'drills isregulated by a conventional 'stpinotf'shwm to prevent drillinga holethrough the printing plate 80.

Itis believed to be evident that with`p'rintingplates 80 which have been comparatively checked for warpa'ge, twisted images,` and properV size, haverbeen properly centered upon the checking device 88 and have identically positioned and drilled centerholes 120 therein, f that co-operating register pinsmay be placed 'within'fthe auto-miller, not shown, to identicallyiholdtheseveral plates titl of a 'color series while the lanto-millercuts the press cylinder gripping"p0`ckets in the platei80. When each printing plate 80 has'thusfbeen prepared` the plates will needA very little, if'any, adjustment'when placed upon the printing press cylinders.

The `register. marks 84 and 85 have been shown as being depressionsl within the printing plate;v As` an Valterna/tev embodimennthe register mark might well be'njiade in reverse; that is, a raised projection' could rbewplacved upon the top surfaces of the type chase to' cause a depression in the matrix which in turn would cast a conical'- like' register projection 120 upon the printing plate 80, as shown in Fig. 2l. A cup-like .receiver A122, having a conical bore 123 therein, adapted4 to receive the register l projection 120, is rigidly attached to the scriber arm and operates to register the'plate 80 in the samenanner as disclosed hereinabove. Obviously the invention is susceptible to some change or alteration without defeating its'practicability, and I vtherefore do not wish tovv be connedto thep'refe'rred embodiment shown inthe drawings and described herein, further'than I yam limited by Vthescope vof'the'appended dirms? i,
